摘要:
A method for operating a gas and steam turbine plant is provided. In the plant, the flue gas that escapes from a gas turbine is routed through a waste gas steam generator and where a flow medium that is used to drive a steam turbine is conducted in a flow medium circuit that includes several pressure stages. At least one of the pressure stages has an evaporator circuit with a steam collection drum that has a plurality of downpipes connected to the steam collection drum and a plurality of rising pipes downstream of the downpipes that are likewise connected to the steam collection drum and are heated by the flue gas in the waste heat steam generator. The height of the fluid column formed by the flow medium in the downpipes is monitored and a transient dry operation of the evaporator circuit can thus be detected and safeguarded against.

The invention relates to a waste heat steam generator of a gas fired and steam powered generator. Said generator comprises a waste heat boiler to which exhaust gas of a gas turbine can be supplied. Said steam generator also comprises at least one evaporator which is located in the waste heat boiler and is used to produce process steam for a steam turbine. According to the invention, flue gas from a heating device can be supplied to the waste heat boiler and at least part of said flue gas can be extracted at at least one point of the waste heat boiler and redirected back to the inlet of said waste heat boiler.

A dishwasher includes a washing chamber defining a washing volume in which items to be washed are disposed and a storage container disposed in the washing chamber for retaining items at a predetermined storage location within the washing volume. A spray device is provided that is operable to spray at least one jet of liquid and a dissolving chamber having a chamber floor with at least one aperture is mounted to the storage container. The storage container and the spray device are mounted relative to one another such that the dissolving chamber is wetted with liquid that has been sprayed by the spray device.

The invention relates to a device for electrically stimulating biological material that can be electrically stimulated. Said device comprises an electrode array which can be implanted so as to be in active contact with the biological material. Said electrode array comprises a two-dimensional arrangement of individual electrodes (Eij) that produce a stimulation field (S1, S2,) for the biological material when impinged upon with a stimulation signal, and means (2) for impinging the individual electrodes with the stimulation signals. The electrode impinging means for impinging the individual electrodes with alternating field stimulation signals is configured in such a manner that the electrode impinging means (2) for impinging the individual electrodes (Eij) with alternating field stimulation signals (Vij) is configured in such a manner that the electrode array (1) comprises at least two tripolar or higher multipolar multipole elementary cells (T1, T2,; Q1, Q2,) from three or more adjacent individual electrodes each, and the stimulation fields (S1, S2,) produced by every multipole elementary cell for the biological material has a rotational component, and at least one of the individual electrodes pertains to at least two multipole elementary cells. The invention also relates to the use of the inventive device, e.g. for retina implants.

A combined cycle power plant (100) utilizing a compressor air bleed (62) as a source of heat for generating steam in a steam generator (78) for supplying the gland seals of the steam turbine (3) and as a motive force for an air ejector (90) for evacuating the condenser (8) during plant start-up. The compressor air bleed avoids delay awaiting the availability of steam from the heat recovery steam generator (4) without the need for an auxiliary boiler.

A hearing aid housing comprises at least two housing shells and a battery compartment that can be brought into different swiveled positions. In order to simplify the structuring of the hearing aid, all mounts of the battery compartment hinge as well as catch means for producing the various swiveled positions are inventively situated at one housing shell. This facilitates the observation of tolerances in the manufacture of the hearing aid. The battery compartment is also firmly seated at one housing shell and can not separate or wobble during further assembly of the hearing aid.

A seal is provided between the door apron and the lip of the container in a dishwasher, enabling a high sealing performance to be obtained during the entire service life of the dishwasher and providing an esthetic design. The seal can be mounted in a reliable manner without any considerable expenditure of force, recycling of a used seal is possible via appropriate selection of materials and the seal can withstand the dynamic strain put upon the door seal of a dishwasher. The dishwasher is provided with a door seal which is made of an elastic synthetic material, consisting of a fixing area for connection to the edge of a rinsing container, a sealing element for arrangement on the underside of a dishwasher and which is arranged between the fixing area, and a sealing element, wherein the fixing area, sealing element and sealing strip form a single part.
